Spiking dynamics of frequency upconverted field generated in continuous-wave excited rubidium vapors

A. M. Akulshin, Nafia Rahaman, Sergey A. Suslov +2 more

We report on spiking dynamics of frequency upconverted emission at 420 nm generated on the 6 P 3 / 2 − 5 S 1 / 2 transition in Rb vapor two-photon excited to the 5 D 5 / 2 level with laser light at 780 and 776 nm. The spike duration is shorter than the natural lifetime of any excited level involved in the interaction with both continuous and pulsed pump radiation. The spikes at 420 nm are attributed to temporal properties of the directional emission at 5.23 µm generated on the population-inverted 5 D 5 / 2 − 6 P 3 / 2 transition. A link between the spiking regime and cooperative effects is discussed. We suggest that the observed stochastic behavior is due to the quantum-mechanical nature of the cooperative effects rather than random fluctuation of the applied laser fields.We report on spiking dynamics of frequency upconverted emission at 420 nm generated on the 6 P 3 / 2 − 5 S 1 / 2 transition in Rb vapor two-photon excited to the 5 D 5 / 2 level with laser light at 780 and 776 nm.

Semiconductor laser with133Cs vapor external selective mirror

Vladimir L Velichansky, Alexander S. Zibrov, V V Nikitin +3 more

Pulsed stimulated emission near the D2 line of 133Cs (852.1 nm) was obtained from a semiconductor laser with an external selective element utilizing specular reflection from a cesium vapor cell. The power and spectral width of the stimulated emission at a vapor pressure of 2 Torr were 1 mW and 5×10−3 nm, respectively. Investigations were made of the spectral and temporal characteristics of the laser radiation at different cesium vapor pressures. An analysis was made of the conditions needed to enhance substantially the average stimulated emission power. The possibility of using a laser with an external selectively reflecting cell for optical pumping of alkali metal vapors is discussed. The resonance absorption lines of rubidium and potassium were recorded using a pulsed injection laser.Pulsed stimulated emission near the D2 line of 133Cs (852.1 nm) was obtained from a semiconductor laser with an external selective element utilizing specular reflection from a cesium vapor cell.
